FOOD-GRINDER.

Specification of Letters Patent.

Application filed March 16, 1912.

Patented July 29, 1913.

Serial No. 684,318.

1/ '0 all whom it may concern Be it known that I, UTAJIRO KAWASAKI, asubject of the Emperor of Japan, residing at Los Angeles, in the countyof Los Angeles and State of California, have invented a new and usefulFood-Grinder, of which the following is a specification.

My invention relates to a food grinder for preparing edibles forcooking, and is particularly adapted for grinding fish into a pulp sothat the same may be made into convenient form for use in making fishcakes or other similar articles of food, and one of the objects of myinvention is to produce a machine for grinding food of the characterdescribed of simple form and construction which may be efficientlyoperated for the purposes for which the machine is designed.

Referring to the drawings, which are for illustrative purposes only:Figure 1 is a side elevation, partly in sect-ion, of a machine embodyinga form of my invention. Fig. 2 is a sectional, plan view on line m. mFig. 1. Fig. 3 is an enlarged sectional view of a portion of the bowlshowing the roughened inner face of the bowl.

The machine comprises a bowl 1 formed by hollowing out a block 2 ofconcrete, rock or other similar substance. The walls 3 of the bowl arespherical in form and extend inwardly as indicated at 41, thelip 5 ofthe bowl being of smaller diameter than the central portion of the bowl.In making the bowl, the walls thereof are left in a roughened state forthe purposes hereinafter described. Mounted on the upper face of theblock 2 are four uprights 7 secured at their upper ends by means ofsuitable bolts to a head 8, which head 8 forms a bearing for a verticalshaft 9 supported on the head 8 by means of a collar 10 having asuitable pin 11 which extends through the collar and the shaft 9therein. Mounted on the upper end of the shaft 9 is a pulley 12 adaptedto be driven by a belt 13 from any suitable source of power, not shown.

Secured in any suitable manner to the lower end of the shaft 9 is acollar 15 terminating in a pair of jaws 16 adapted to receive and clamptherebetween a plate 17 The plate 17 is provided with a pair of hollowbosses 18, each adapted to have secured therein by means of pins 19 anarm 20. Secured to the lower end of each arm 20 is a heating or grindingmeans which consists of a head 22 formed of hard wood, in the presentinstance lignum vitae. The outer end or face 23 of each head 22 isrounded to conform to the shape of the inner walls of the bowl 1. Theheads 22 in general form closely approximate the frustum of a cone, thelargest end of the cone terminating in the face: 23 just described. Theplate 17 may be set in different angular positions in the jaws 16 andmay be held in any desired position by means of a set screw 25 pro videdwith handle means 26. The plate 17 is preferably set in the jaws 16 in aposition so that the heads 22 when rotated within the bowl each have adifferent path of movement, as indicated in full line position in Fig.1, it being understood that the relative position of the heads 22remains unchanged and that the movement of the plate 17 in the jaws 16swings both of the heads in unison, a different position of the headsbeing illustrated in dotted lines in Fig. 1. The shaft 9 is kept inproper alinement so that the heads rotate within the bowl by means of abearing 30 adapted to engage'the shaft 9 above the bowl, which bearing30 is supported on a brace 31 secured to the standard or upright 7 bymeans of suitable rivets or bolts 32, one end 33 of the brace 31extending outwardly from the frame and having pivotally mounted there toa link 34:, to the upper end of which is pivotally mounted at 35 anoperating arm 36 having a handle means 37 formed at one end thereof. Theoperating arm 36 is provided with a strap 40 which passes around theshaft 9 and is adapted to engage the under face of a collar 41 securedto the shaft by means of a suitable pin 42.

The machine is particularly designed for rendering fresh fish to a pulppreparatory to the boiling of the same in the preparation of the fishfor use in making fish cakes and similar materials, and in such use themachine is operated in the following man ner.

The operating arm 36 is raised by the handle means 37 the strap 40 onthe operating arm thereby raising the shaft 9 by means of the collar 41being engaged by the strap 40 on the operating arm 36. The fish is thenplaced in the bowl 1 and the operating arm moved downwardly so that theheads 22 come into contact with the fish. The shaft 9 is then rotatedthrough the medium of pulley 12 and belt 13 and the shaft graduallylowered into the mass of fish in the bowl. The rotation of the shaft 9is continued until the mass of fish in the bowl has become of the properconsistency, after which the machine is stopped and the fish removedfrom the bowl. During the operation of reducing the fish to the propercon sistency, as above referred to, the fish is not only stirred againstthe roughened sides of the bowl by the beating, as of the heads 22 intheir rotativemovement, but the fish also is mashed between the faces'23of the heads 22 and the roughened sides of the bowl, thereby reducingthe fish to a pulp. The lip-5 formed on the bowl extends inwardly asufficient distance so that the rotating action of the heads 22 in thebowl does not throw the contents of the bowl onto the surroundingobjects, but directs the contents if thrown toward the center of thebowl so that the contents drops within the-bowl.

hat I claim is V 1. A food grinder comprising a bowl, a shaft verticallymounted above said bowl, a plate pivotally mounted in thelower end ofsaid shaft. a plurality of rigid arms secured to said plate, a head oneach arm adapted to engage the inner walls of said bowl, means forclamping said plate to said shaft, means for longitudinally raising andlowering said shaft, and means for rotating said shaft.

2. A food grinder comprlslng a bowl havmg a rough lnner wall, a circular11p on the upper edge of said bowl extending inwardly therefrom,standards secured to said bowl,

a shaft vertically mounted in said standards, a pair of rigid'armspivotallymounted in the lower end ofsaid shaft, a head on each arm,means'for clamping said head to said shaft, each head having a facethereon adapted to conform to the inner wall of said-bowl, means forlongitudinally raising and lowering said shaft, and means for rotatingsaid shaft.

3. A food grinder comprising a bowl hav- -ing: a spherical inner face, acircular lip on the upper edge of said bowl extendinginwardly therefrom,standards secured to said bowl, a shaft vertically mounted in saidstandards, a plate pivotally mounted in the lower end of said shaft, apair of arms secured to said plate, means for securing said plate to thelower end of said shaft, a head on each arm, ea'chheadhaving a'facethereon adapted to conform to the inner wall of said bowl, an operatingarm pivotally end of saidshaft, ahead on each arm, each head having aface thereon adapted'to conform to the innerwall of-said bowl, a linkpivotally mounted on said standards, an operating arm pivotallymountedto the end of said links, a collaron saidshaft adapted to be engaged bysaid operating arm,-and

means for rotating said shaft.

In testimony whereof, I have hereunto set my hand at Los Angeles,Gallfornia, this 7th day of March, 1912.
